2. How many square meters of facing limestone were needed?

**Henry**, Monday, June 27, 2011 at 2:46pm1. V = Ab*h/3. Ab = Area of the base.

V = (230)^2 * 146/3 = 2,574,467m^3.

2. Al = P*Hs / 2.

P = 4 * 230 = 920m = Perimeter of the base.

Hs^2 = (b/2)^2 + h^2,

Hs^2 = (230 / 2)^2 + (146)^2 = 34,541

Hs = 186m = Slant Height.

Al = 920 * 186 / 2 = 85,560m^2 = Lateal

area = Amount of limestone needed.
